Description

本発明は、製本装置の本身搬送機構、詳しくは各製本処理工程を周回移動する複数のクランパーを備えた製本機における各クランパーの開き幅調整機構に関するものである。   The present invention relates to a body conveying mechanism of a bookbinding apparatus, and more particularly to an opening width adjusting mechanism of each clamper in a bookbinding machine provided with a plurality of clampers that move around each bookbinding processing step.

図９は無線綴じ製本装置の一例の概略の構成を示す図、図１０は図９の製本装置の製本処理工程を説明する説明図であり、図９及び図１０を参照して簡単に説明すると、製本装置１はクランプ部２、ミーリング部３、糊付け部４、表紙張り付け部５が設けられ、可動クランプ板７と固定クランプ板８を備えるクランパー６が各部を順に移動するように構成されている。   FIG. 9 is a diagram showing a schematic configuration of an example of the saddle stitching apparatus, and FIG. 10 is an explanatory diagram for explaining a bookbinding process of the bookbinding apparatus of FIG. 9, which will be briefly described with reference to FIGS. The bookbinding apparatus 1 is provided with a clamp part 2, a milling part 3, a gluing part 4, and a cover sticking part 5, and a clamper 6 including a movable clamp plate 7 and a fixed clamp plate 8 is configured to move each part in turn. .

クランプ部２は、例えば、印刷機や複写機等から送られた葉紙１５を頁順に積み重ね、一冊分積み重ねた枚葉紙（以下、「本身」という。）１６をクランパー６の可動クランプ板７と固定クランプ板８の間に、本身１６の背面１８をレベル板９側にして挿入し、挿入された本身１６を可動クランプ７の固定クランプ８側への移動、すなわちクランパー６を閉じて本身１６をクランパー６に挾持させる部（本身１６の製本処理開始工程）である。   The clamp unit 2 is configured such that, for example, sheets 15 sent from a printing machine, a copier, or the like are stacked in the order of pages, and one sheet of stacked sheets (hereinafter referred to as “body”) 16 is a movable clamp plate of the clamper 6. 7 and the fixed clamp plate 8 are inserted with the back surface 18 of the main body 16 facing the level plate 9, and the inserted main body 16 is moved to the fixed clamp 8 side of the movable clamp 7, that is, the clamper 6 is closed and the main body is closed. 16 is a part that holds the clamper 6 on the clamper 6 (the bookbinding process starting step of the body 16).

ミーリング部３は、クランプ部２でクランパー６に挾持された本身１６の背面１８をフライス盤１０により面一に揃える部（本身１６のミーリング処理工程）である。糊付け部４は、ミーリング部３で面一に揃えられた本身１６の背面１８に糊付け機１１により糊付けする部（本身１６の糊付け処理工程）である。ミーリング部３及び糊付け部４での作業は、本身１６をクランパー６に挾持させたままでクランパー６の移動とともに行なわれる。   The milling unit 3 is a unit that aligns the back surface 18 of the main body 16 held by the clamper 6 with the clamp unit 2 by the milling machine 10 (milling process step of the main body 16). The gluing part 4 is a part (gluing process step of the main body 16) that is glued by the gluing machine 11 to the back surface 18 of the main body 16 that is flush with the milling unit 3. The operations at the milling unit 3 and the gluing unit 4 are performed along with the movement of the clamper 6 while the body 16 is held by the clamper 6.

表紙張り付け部５は、予め表紙ストッカー（あるいは給紙台）の表紙１７の１枚がニップ板（締め板）１２、１３上に運ばれて、所定の位置に位置決めされてあり、表紙１７のニップ板１２、１３の間に位置する上部にクランパー６に挟持された背面１８に糊付けされた本身１６を位置させ、ニップ板１２、１３及び底板１４、すなわち表紙張り付け機５を少し上昇させ、本身１６を、表紙１７を挟んでニップ板１２、１３の間の底板１４の上に当て本身１６の背面１８に表紙１７を貼着し、ほぼ同時にニップ板１２、１３を移動して本身１６の背面１８側の縁辺部近傍を両側から締め付けて表紙１７を折り込み、表紙１７を本身１６に沿わせる表紙付けする部（表紙付け処理工程）である。   The front cover pasting unit 5 has a front cover 17 of a front cover stocker (or paper feed table) that has been transported onto the nip plates (clamping plates) 12 and 13 in advance and positioned at a predetermined position. The main body 16 glued to the back surface 18 sandwiched by the clamper 6 is positioned on the upper part located between the plates 12 and 13, and the nip plates 12 and 13 and the bottom plate 14, that is, the cover pasting machine 5 are slightly raised, and the main body 16 The cover 17 is applied to the back surface 18 of the main body 16 on the bottom plate 14 between the nip plates 12 and 13 with the cover 17 interposed therebetween, and the nip plates 12 and 13 are moved almost simultaneously to move the back surface 18 of the main body 16. This is a part (covering process step) for attaching a cover so that the vicinity of the side edge is tightened from both sides and the cover 17 is folded and the cover 17 is placed along the body 16.

製本装置は上記のように構成されているが、本身１６を挾持して各処理工程を移動するクランパー６は、搬送チェーンに固定された固定クランプ板８と、この固定クランプ板８と対向する可動クランプ板７とを有し、可動クランプ板７は固定クランプ板８に接近する方向にバネにより附勢されており、本身１６はこの附勢力で固定クランプ板８と可動クランプ板７とで挾持される。可動クランプ板７と固定クランプ板８との間に本身１６を挿入するときは、カムによりバネ力に抗して可動クランプ板７を固定クランプ板８から押し離して（以下、クランパーを開くという。）挿入するように構成されている。   Although the bookbinding apparatus is configured as described above, the clamper 6 that holds the main body 16 and moves each processing step includes a fixed clamp plate 8 that is fixed to the transport chain, and a movable that faces the fixed clamp plate 8. The movable clamp plate 7 is biased by a spring in a direction approaching the fixed clamp plate 8, and the body 16 is held between the fixed clamp plate 8 and the movable clamp plate 7 by this biasing force. The When the body 16 is inserted between the movable clamp plate 7 and the fixed clamp plate 8, the movable clamp plate 7 is pushed away from the fixed clamp plate 8 against the spring force by a cam (hereinafter referred to as opening the clamper). ) Is configured to insert.

ところで、クランパー６で挟持する本身１６の厚みは様々であり、厚みの薄い本身の場合、カムによるクランパーの開き幅が大きいと、クランパーに挿入した本身１６が背崩れを発生する。この背崩れを発生させないためには、クランパーの開き幅を本身１６の厚みに応じて調整する必要がある。この調整を、クランパーにクランパーの可動板と螺合する開き幅調整ネジ軸を設け、往復移動の終端部に位置する本身の挿入位置でその開き幅調整ネジ軸を回転し、これによりクランパーの固定板と可動板の開き幅の調整を行なうものがある。
特開平９−２２０８７６号公報 By the way, the thickness of the main body 16 clamped by the clamper 6 varies, and in the case of a thin main body, if the opening width of the clamper by the cam is large, the main body 16 inserted into the clamper will be reversed. In order not to cause this collapse, it is necessary to adjust the opening width of the clamper according to the thickness of the body 16. For this adjustment, the clamper is provided with an opening width adjustment screw shaft that is screwed with the movable plate of the clamper, and the opening width adjustment screw shaft is rotated at the insertion position of the body located at the end of the reciprocating movement, thereby fixing the clamper. Some adjust the opening width of the plate and the movable plate.
Japanese Patent Laid-Open No. 9-220876

しかし、この調整は製本処理工程を往復移動する移動の終端部を有する１つのクランパーを備えた製本装置においては好都合であるが、周回移動する搬送チェーンに所定の間隔で複数のクランパーを設け、各クランパーに順次本身を挟持させて各製本処理工程を移動させる移動の終端部を有しない製本装置には適用できず、一般的に、クランパーを開閉するカムのストロークを大きくし、その位置を本身の厚みに応じて変更することによりクランパーの開き幅調整が行われている。   However, this adjustment is convenient in a bookbinding apparatus having one clamper having a movement end portion that reciprocates in the bookbinding process, but a plurality of clampers are provided at predetermined intervals on a circularly moving transport chain, It cannot be applied to a bookbinding apparatus that does not have a terminal portion for moving each bookbinding process by holding the body in sequence with the clamper.In general, the stroke of the cam that opens and closes the clamper is increased, and the position of the body is changed. The opening width of the clamper is adjusted by changing the thickness according to the thickness.

このようにクランパーを開閉するカムのストロークを大きくし、その位置を本身の厚みに応じて変更する調整では、クランパーの開き幅を大きく変更しても挟持力に差が発生しないように、非常に長いバネを各クランパーに組み込んでバネ常数を下げており、そのためにクランパーが大型化し、また、クランパーを開閉するカムの形状も複雑としなければならないという問題があった。   The adjustment that increases the stroke of the cam that opens and closes the clamper and changes its position according to the thickness of the body, so that there is no difference in clamping force even if the opening width of the clamper is changed greatly. A long spring is incorporated into each clamper to lower the spring constant, which causes a problem that the size of the clamper increases and the shape of the cam that opens and closes the clamper must be complicated.

本発明が解決しようとする課題は、周回移動する搬送手段に所定の間隔で複数のクランパーを設け、各クランパーに本身を挟持して各製本処理工程を移動させてなる製本装置における各クランパーの開き幅の調整を、クランパーを大型化することなく簡単かつ簡素な機構で行えるようにし、斯かる問題を解消する点にある。   The problem to be solved by the present invention is to open each clamper in a bookbinding apparatus in which a plurality of clampers are provided at a predetermined interval on a conveying means that moves in a circular manner, and each bookbinding processing step is moved while holding the body between each clamper. The width adjustment can be performed with a simple and simple mechanism without increasing the size of the clamper, and the problem is solved.

本発明は、周回移動する搬送手段に所定の間隔で複数のクランパーを設け、各クランパーの固定板とバネにより前記固定板側へ付勢された可動板との間に本身を挟持して製本処理工程を順次移動させてなる製本装置の本身搬送機構において、前記クランパーは一端にギアが固定され前記可動板と螺合し、前記ギアの回転で前記固定板と可動板の開き幅を調整する開き幅調整ネジ軸を具えるとともに、前記周回移動する一箇所に、前記ギアと噛合するギアを有し前記開き幅調整ネジ軸を回転駆動するネジ軸駆動機構を移動可能に配置し、クランパーの開き幅調整時、前記ネジ軸駆動機構を移動し、前記ネジ軸駆動機構のギアと前記クランパーのギアと噛合して前記開き幅調整ネジ軸を回転駆動して前記クランパーの開き幅を調整してなることを主な特徴とする。   The present invention provides a bookbinding process in which a plurality of clampers are provided at predetermined intervals on a conveying means that moves around, and the body is sandwiched between a fixed plate of each clamper and a movable plate that is biased toward the fixed plate by a spring. In the body conveying mechanism of the bookbinding apparatus that is sequentially moved in the process, the clamper has a gear fixed to one end and is screwed with the movable plate, and the opening that adjusts the opening width of the fixed plate and the movable plate by the rotation of the gear. In addition to having a width adjusting screw shaft, a screw shaft driving mechanism that rotationally drives the opening width adjusting screw shaft having a gear that meshes with the gear is provided at one place of the circular movement so that the clamper can be opened. When adjusting the width, the screw shaft drive mechanism is moved, the gear of the screw shaft drive mechanism and the gear of the clamper are engaged, and the opening width adjustment screw shaft is rotationally driven to adjust the opening width of the clamper. That And features.

本発明では、周回移動する搬送手段に固定した複数のクランパーの各々に開き幅調整ネジ軸を設けるとともに、複数のクランパーが周回移動する一箇所に、前記開き幅調整ネジ軸を回転駆動する移動可能のネジ軸駆動機構を配置し、クランパーの開き幅調整時、ネジ軸駆動機構を移動してネジ軸駆動機構の駆動で順次複数のクランパーの開き幅を調整するので、各クランパーは開き幅調整用の駆動機構を備えずその構成を簡素かつ軽量とすることができ、また、１つのネジ軸駆動機構で複数のクランパーの開き幅を調整するため、クランパーの開き幅の調整に必要とする機構が少なく、その機構に要するコストを低減することができる。   In the present invention, each of the plurality of clampers fixed to the circumferentially moving conveying means is provided with an opening width adjusting screw shaft, and the opening width adjusting screw shaft can be driven to rotate at one place where the plurality of clampers move around. The screw shaft drive mechanism is arranged, and when adjusting the clamper opening width, the screw shaft drive mechanism is moved to adjust the open width of multiple clampers sequentially by driving the screw shaft drive mechanism. The mechanism required for adjusting the opening widths of the clampers can be reduced by adjusting the opening widths of the plurality of clampers with a single screw shaft driving mechanism. Therefore, the cost required for the mechanism can be reduced.

周回移動する搬送手段に所定の間隔で複数のクランパーを設け、各クランパーに本身を挟持して各製本処理工程を移動させてなる製本装置における各クランパーの開き幅の調整を、クランパーを大型化することなく簡単かつ簡素な機構で行えるようにする目的を、開き幅調整ネジを各クランパーに設け、各クランパーが通過する一箇所に、クランパーの開き幅調整時、クランパーの開き幅調整ネジを回転駆動するネジ軸駆動機構を設けることにより実現した。   Adjusting the opening width of each clamper in a bookbinding apparatus in which a plurality of clampers are provided at a predetermined interval on the conveying means that moves around, and the bookbinding process is performed by holding the body between each clamper and enlarging the clamper Opening adjustment screw is provided in each clamper for the purpose of enabling easy and simple mechanism without any trouble, and when adjusting the opening width of the clamper, the opening adjustment screw of the clamper is rotationally driven at one place where each clamper passes. This is realized by providing a screw shaft drive mechanism.

図１において、２１は図９および図１０に示す製本処理工程を周回移動する搬送チェーン、２２はクランパー、２３はネジ軸駆動機構、２４はクランパーの開き幅を検出する検出機構、２５はカム機構、２６は本身である。本実施例では製本処理工程を周回移動する搬送チェーン２１に４個のクランパー２２が一定の間隔を隔てて固定されており、各クランパー２２は、搬送チェーン２１に固定された固定板２２ａと、固定板２２ａと対向する可動板２２ｂと、カムレバー当接板２２ｃおよび支持板２２ｄとを有し、支持板２２ｄは両端部でカムレバー当接板２２ｃと支持軸２２ｅで固定されている。支持軸２２ｅは、固定板２２ａと可動板２２ｂとを貫通している。   In FIG. 1, 21 is a transport chain that circulates in the bookbinding process shown in FIGS. 9 and 10, 22 is a clamper, 23 is a screw shaft drive mechanism, 24 is a detection mechanism that detects the opening width of the clamper, and 25 is a cam mechanism. , 26 is the body. In this embodiment, four clampers 22 are fixed at a fixed interval to a transport chain 21 that orbits the bookbinding process, and each clamper 22 is fixed to a fixed plate 22a fixed to the transport chain 21. It has a movable plate 22b facing the plate 22a, a cam lever contact plate 22c and a support plate 22d, and the support plate 22d is fixed at both ends by a cam lever contact plate 22c and a support shaft 22e. The support shaft 22e passes through the fixed plate 22a and the movable plate 22b.

可動板２２ｂは、その両側の端部で支持板２２ｄに回転自在に固定支持した調整ネジ軸２２ｆと螺合し、一方の調整ネジ軸２２ｆの支持板２２ｄから突出する端部にギア２２ｇが固定され、この調整ネジ軸２２ｆの回転はタイミングベルト２２ｈを介して他方の調整ネジ軸２２ｆに伝達される。このギア２２ｇを回転すると両側の調整ネジ軸２２ｆが回転し、可動板２２ｂは支持板２２ｄから離れ、固定板２２ａに接近する。すなわち、ギア２２ｇを回転した分可動板２２ｂは固定板２２ａに接近し、また可動板２２ｂは固定板２２ａから離れ、ギア２２ｇの回転操作でクランパー２２の最大の開き幅が調整される。この開き幅を検出するために可動板２２ｂの先端部には、検出板２２ｊが固定されている。   The movable plate 22b is threadedly engaged with an adjustment screw shaft 22f fixed to and supported by the support plate 22d at both ends thereof, and a gear 22g is fixed to the end of the adjustment screw shaft 22f protruding from the support plate 22d. The rotation of the adjusting screw shaft 22f is transmitted to the other adjusting screw shaft 22f via the timing belt 22h. When this gear 22g is rotated, the adjustment screw shafts 22f on both sides rotate, and the movable plate 22b moves away from the support plate 22d and approaches the fixed plate 22a. That is, as the gear 22g is rotated, the movable plate 22b approaches the fixed plate 22a, the movable plate 22b moves away from the fixed plate 22a, and the maximum opening width of the clamper 22 is adjusted by rotating the gear 22g. In order to detect the opening width, a detection plate 22j is fixed to the tip of the movable plate 22b.

固定板２２ａとカムレバー当接板２２ｃとの間にバネ２７が配置され、このバネ２７は、固定板２２ａをカムレバー当接板２２ｃから離す方向、つまり可動板２２ｂを固定板２２ａに引き寄せる方向に附勢している。この附勢力により移動中のクランパーは本身２６を挟持する。すなわち、カムレバー当接板２２ｃにカムレバーの端部が当接してバネ２７のバネ力に抗して押し込まれると、カムレバー当接板２２ｃ、両側の支持軸２２ｅ、支持板２２ｄが一体となって移動し、両側の調整ネジ軸２２ｆを介して支持板２２ｄに固定された可動板２２ｂが固定板２２ａから離れる方向に移動してクランパー２２を開く。この開いた状態で本身２６を挿入し、カムレバーの端部の押し込みが解除されるとその本身２６をバネ２７のバネ力で挟持して移動することとなる。このときの開き幅は両側の調整ネジ軸２２ｆの回転量で調整される。   A spring 27 is disposed between the fixed plate 22a and the cam lever abutting plate 22c, and the spring 27 is attached in a direction in which the fixed plate 22a is separated from the cam lever abutting plate 22c, that is, in a direction in which the movable plate 22b is pulled toward the fixed plate 22a. It is fast. The moving clamper clamps the body 26 by this urging force. That is, when the end of the cam lever comes into contact with the cam lever contact plate 22c and is pushed against the spring force of the spring 27, the cam lever contact plate 22c, the support shafts 22e on both sides, and the support plate 22d move together. Then, the movable plate 22b fixed to the support plate 22d via the adjustment screw shafts 22f on both sides moves in a direction away from the fixed plate 22a to open the clamper 22. When the main body 26 is inserted in the opened state and the pushing of the end portion of the cam lever is released, the main body 26 is moved by being sandwiched by the spring force of the spring 27. The opening width at this time is adjusted by the amount of rotation of the adjusting screw shafts 22f on both sides.

支持板２２ｄには、一端を支点として揺動するブレーキ板２２ｉが取り付けられ、そのブレーキ板２２ｉにブレーキ２２ｌが取り付けられており、通常ブレーキバネ２２ｋ（図５、図７参照）でブレーキ板２２ｉを介してブレーキ２２ｌでタイミングベルト２２ｈを押え両側の調整ネジ軸２２ｆの回転を抑制している。両側の調整ネジ軸２２ｆを回転するとき、すなわちクランパー２２の開き幅を調整するときには、そのバネ力に抗してブレーキ板２２ｉを押し上げブレーキ２２ｌをタイミングベルト２２ｈから離して両側の調整ネジ軸２２ｆを回転する。   The support plate 22d is attached with a brake plate 22i that swings around one end as a fulcrum. A brake 22l is attached to the brake plate 22i, and the brake plate 22i is normally attached to the brake plate 22i (see FIGS. 5 and 7). The timing belt 22h is pressed by the brake 22l and the rotation of the adjusting screw shafts 22f on both sides is suppressed. When the adjustment screw shafts 22f on both sides are rotated, that is, when the opening width of the clamper 22 is adjusted, the brake plate 22i is pushed up against the spring force to release the brake 22l from the timing belt 22h and the adjustment screw shafts 22f on both sides are moved. Rotate.

カム機構２５、ネジ軸駆動機構２３および検出機構２４は、クランパー２２が周回移動する一箇所に配置され、その箇所に位置するクランパー２２を開き、その開き幅の調整および開き幅の検出を行なう。カム機構２５は、モータＭ１の回転で回転するカム板２５ａとカム板２５ａの山と谷からなるカム面に沿って揺動するカムレバー２５ｂからなり、カムレバー２５ｂの一端はカム板２５ａのカム面に当接し、カム山の当接でカムレバー２５ｂの他端がその箇所に位置するクランパー２２のカムレバー当接板２２ｃに当接して押し込みクランパー２２を開く。本実施例では、この開きで挟持した製本処理後の本身２６を排出し、新たに製本処理する本身２６を挿入する。   The cam mechanism 25, the screw shaft drive mechanism 23, and the detection mechanism 24 are arranged at one place where the clamper 22 moves around, opens the clamper 22 located at that place, adjusts the opening width, and detects the opening width. The cam mechanism 25 includes a cam plate 25a that rotates by the rotation of the motor M1 and a cam lever 25b that swings along a cam surface that includes a peak and a valley of the cam plate 25a. One end of the cam lever 25b is located on the cam surface of the cam plate 25a. The other end of the cam lever 25b comes into contact with the cam lever contact plate 22c of the clamper 22 located at that position by the contact of the cam crest, and the push-in clamper 22 is opened. In the present embodiment, the bookbinding-processed main body 26 sandwiched by the opening is discharged, and a new bookbinding processing body 26 is inserted.

ネジ軸駆動機構２３は、モータＭ２の回転で上下動するリンク２３ａに連結された保持板２３ｂと、この保持板２３ｂに固定された、回転軸にギア２３ｃを固定したモータＭ３からなり、モータＭ２の回転でギア２３ｃは上下し、上部に位置するときギア２３ｃと調整ネジ軸２２ｆのギア２２ｇと噛合する。この噛合でモータＭ３を駆動し、ギア２３ｃを回転させ、その回転をギア２２ｇに伝達して調整ネジ軸２２ｆを回転し、可動板２２ｂの位置を調整する。すなわちクランパー２２の開き幅を調整する。また、保持板２３ｂには、ブレーキローラ２３ｄが取り付けられており、保持板２３ｂが上部に位置するときクランパー２２のブレーキ板２２ｉを押し上げ、ブレーキ２２ｌをタイミングベルト２２ｈから離し調整ネジ軸２２ｆの回転の抑制を解除する。   The screw shaft drive mechanism 23 includes a holding plate 23b connected to a link 23a that moves up and down by the rotation of the motor M2, and a motor M3 fixed to the holding plate 23b and having a gear 23c fixed to the rotation shaft. Rotation of the gear 23c moves up and down and meshes with the gear 23c and the gear 22g of the adjusting screw shaft 22f when positioned at the upper part. By this engagement, the motor M3 is driven, the gear 23c is rotated, the rotation is transmitted to the gear 22g, the adjustment screw shaft 22f is rotated, and the position of the movable plate 22b is adjusted. That is, the opening width of the clamper 22 is adjusted. A brake roller 23d is attached to the holding plate 23b. When the holding plate 23b is located at the upper part, the brake plate 22i of the clamper 22 is pushed up, the brake 22l is separated from the timing belt 22h, and the adjusting screw shaft 22f is rotated. Release the suppression.

検出機構２４は、モータＭ４の回転で回転するネジ２４ｄと、このネジ２４ｄと螺合しネジ２４ｄの回転でクランパー２２に接近しまた離れる方向に移動するアーム２４ｂと、アーム２４ｂの先端に固定された近接スイッチなどの検出器２４ａとからなり、検出器２４ａは可動板２２ｂに固定した検出板２２ｊを検出する。この検出でモータＭ３を駆動してクランパー２２の開き幅を設定する。   The detection mechanism 24 is fixed to a screw 24d that rotates by the rotation of the motor M4, an arm 24b that is screwed with the screw 24d and moves in the direction of approaching and moving away from the clamper 22 by the rotation of the screw 24d, and the tip of the arm 24b. The detector 24a detects a detection plate 22j fixed to the movable plate 22b. By this detection, the motor M3 is driven to set the opening width of the clamper 22.

そして、図１〜図４に示すように可動板２２ｂに固定した検出板２２ｊが検出器２４ａと対向する位置にあるとき、調整ネジ軸２２ｆのギア２２ｇはネジ軸駆動機構２３のギア２３ｃと対向する位置にあり、カムレバー２５ｂは検出器２４ａとギア２３ｃの中間に位置している。すなわちクランパー２２はこの定位置で停止するようにされており、この停止時にクランパー２２の開き幅を調整する。 1 to 4, when the detection plate 22j fixed to the movable plate 22b is at a position facing the detector 24a, the gear 22g of the adjustment screw shaft 22f faces the gear 23c of the screw shaft drive mechanism 23. The cam lever 25b is positioned between the detector 24a and the gear 23c. That is, the clamper 22 is stopped at this fixed position, and the opening width of the clamper 22 is adjusted at the time of the stop.

具体的には、図８に示すように検出器２４ａを調整する位置に移動させる。クランパー２２は検出器２４ａと検出板２２ｊが対向する位置で停止し、カムレバー２５ｂで開かれる。その状態でネジ軸駆動機構２３のギア２３ｃを上昇させ調整ネジ軸２２ｆのギア２２ｇと噛み合わせとともに、図５に示すようにブレーキローラ２３ｄでクランパー２２のブレーキ板２２ｉを押し上げ、ブレーキ２２ｌをタイミングベルト２２ｈから離して調整ネジ軸２２ｆの回転の抑制を解除する。つづいて検出器２４ａが検出板２２ｊを検出しているか否かを判断する。   Specifically, as shown in FIG. 8, the detector 24a is moved to a position to be adjusted. The clamper 22 stops at a position where the detector 24a and the detection plate 22j face each other, and is opened by the cam lever 25b. In this state, the gear 23c of the screw shaft drive mechanism 23 is raised and meshed with the gear 22g of the adjustment screw shaft 22f, and the brake plate 22i of the clamper 22 is pushed up by the brake roller 23d as shown in FIG. The suppression of the rotation of the adjusting screw shaft 22f is released away from 22h. Subsequently, it is determined whether or not the detector 24a detects the detection plate 22j.

検出器２４ａが検出板２２ｊを検出しているときには、モータＭ３を正転し検出器２４ａが検出板２２ｊを検出しなくなるまでクランパー２２の幅を狭め、そのクランパー２２の開き幅の設定を完了する。検出器２４ａが検出板２２ｊを検出していないときには、モータＭ３を逆転し検出器２４ａが検出板２２ｊを検出するまでクランパー２２の幅を広げ、その後モータＭ３を正転し検出器２４ａが検出板２２ｊを検出しなくなるまでクランパー２２の幅を狭め、そのクランパー２２の開き幅の設定を完了する。 When the detector 24a detects the detection plate 22j, the motor M3 is rotated forward to reduce the width of the clamper 22 until the detector 24a no longer detects the detection plate 22j, and the setting of the opening width of the clamper 22 is completed. . When the detector 24a does not detect the detection plate 22j, the motor M3 is rotated in the reverse direction and the width of the clamper 22 is increased until the detector 24a detects the detection plate 22j, and then the motor M3 is rotated forward to detect the detector 24a. The width of the clamper 22 is narrowed until 22j is no longer detected, and the setting of the opening width of the clamper 22 is completed.

１つのクランパー２２の開き幅の設定を完了すると、開き幅未調整のクランパー２２があるか否かを確認する。開き幅未調整のクランパー２２がない場合は全クランパー２２の開き幅の設定は完了しており、クランパー２２の開き幅の調整を終了する。開き幅未調整のクランパー２２がある場合には、図６に示すようにネジ軸駆動機構２３のギア２３ｃを下降させ、クランパー２２を閉じ、図７に示すようにブレーキローラ２３ｄの下降でクランパー２２のブレーキ板２２ｉの押し上げを解除し、ブレーキ２２ｌをタイミングベルト２２ｈに押し付け調整ネジ軸２２ｆの回転を抑制し、開き幅を調整したクランパー２２を移動させる。次の未調整のクランパー２２が定位置で停止する度以上の調整を繰り返し、搬送チェーン２１に固定された全てのクランパー２２の開き幅を順次調整する。 When the setting of the opening width of one clamper 22 is completed, it is confirmed whether or not there is a clamper 22 whose opening width is not adjusted. When there is no clamper 22 whose opening width is not adjusted, the setting of the opening widths of all the clampers 22 is completed, and the adjustment of the opening width of the clampers 22 is finished. When there is a clamper 22 whose opening width is not adjusted, the gear 23c of the screw shaft drive mechanism 23 is lowered as shown in FIG. 6, the clamper 22 is closed, and the clamper 22 is moved down by the brake roller 23d as shown in FIG. The brake plate 22i is lifted up, the brake 22l is pressed against the timing belt 22h, the rotation of the adjusting screw shaft 22f is suppressed, and the clamper 22 whose opening width is adjusted is moved. The above adjustment is repeated each time the next unadjusted clamper 22 stops at a fixed position, and the opening widths of all the clampers 22 fixed to the transport chain 21 are sequentially adjusted.
